SAFETY-Razon.

` of which the following is a specification.

This invention relates to improvements in safety razors and lparticularly to that class of safety( razors the blade of which is given` a transverse motion during Athe cutting process. I l

One of the objects of the invention is to produce simple means for imparting trans- 'verse vibratory movement to the` blade in a manner such as to allow the mechanism to be entirely-inclued in a casing, thereby excluding moisture and dirt from the mechanism,

. and also` arranged so that the casing, to-

gether with the blade and guards, may be quickly 'and conveniently removed and cleaned.

A further object .ofthe invention is to produce a novel way of attaching the guard and blade to the frame or handle of the razor so that they may be conveniently removed, and to provide various forms of guardsso as to adapt the razor to the needs of particular persons or to certain portions of the face.

Of 'the accompanying drawings Figure 1 is an elevation of asafety razor embodying the features'of my invention. Fig. 2 is a fragmental-,view at right angles to Fig.=1 partly in section. Fig. 3 is an enlarged sectional `view of the operating mechanism. Fig. 4 isa section along the line 4 4 of Fig.

V3. Fig. 5 is an end View of the frame of the razor. Fig. 6 is a plan view of the face guard of the razor. Fig. 7 is a plan view of the under side of theJ capguard of the razor.

- Fig. .8 is a plan view of thecutting blade of the razor.. In-general the razor comprises a cutting blade with suitable guards mounted on a frame ixed to a handle, rthe blade being fixed o a vibrator casing which is loosely mounted' in the frame, and which vincloses an electric vibrator. The frame 11 has an opening 12 therethrou h'formed byside walls 13 and 14. A hand ei 15 is fixed, by means of threads 16,-to the `frame. A vibrator casing 17 is looselyv mounted in the opening '12, so

that it is free to vibrate with reference -to the frame, and may be easily slipped from the frame, through either end of the openlng 12. Lugs 18 project outwardly from said casing 17, through an elongated slot 19 the frame. The posts 18 are cylindrical in form, and the outer ends are adapted to pass, through openings 21 in the razor blade 22. When the blade is 1n place on these posts it rests against shoulders 23, and is thus held spaced 'from the casing 17. In this manner the bladeis removably fixed to the casing, and vibrates therewith; but may be readily lifted out wardly from o the posts when the cap guard 30 is removed.

Guides 24 are xed to the upper end ofV the frame 11, upon which is slidably mounted the face guard 25, so that the guard may lbe conveniently removed from the frame by sliding it along the guides. When the razor' isassembled, the posts 18 pass through an elongated opening 26 in they guard, and the blade, supported by said posts, is spaced eX- ternal of the guard a slight distance there-l from. The opening 26 is of such size as to allow the posts to pass freely therethrough, so as to allow a suIicient amount of relative vibration of the posts 18 and the guard 25.-A

Projecting outwardly from the guard 25 are posts 27 which pass loosely through the elongated openings 28 of the blade. The posts 27 pass into an elongated recess 29 in the cap guard 30. The lengths of the posts 27 being such as to space the cap guard.`

guard 25, as indicated in Fig. 2, holding the cap guard firmly '1n place. With this arrangement it will be seen that, when it is desired to clean the instrument, or change the blades, it is necessary only to pull cap guard 30 outwardly away from the face guard; pull the blade 22outwardly from the posts18, and, if desired, the face guard 25 may be removed by removing the casing 17 vin the manner 'hereinafter described.

In order to operate the vibrator, any suitf magnet again closing the circuit, and the able sourcev of electric energy `'may be used;

The electric current is conveyed to the vibrator, by means of the wires and 36. Thesewires are insulated in a common manner, and, 1in this instance, pass through the opening 33 of the handle 15. The wire 36- is passed through another opening 34 in the handle, and is soldered, or fastened in any suitable manner, to the frame 11. Wire 35 j is fastened, in any suitable manner, to a screw 38, which is threaded into anA insulation member 39. The head of the screw 38 is cup shaped, and into the depression 40 projects a screw 41, making'electric contact with the screw 38. The screw 41 is insulated fromthe casing. by means of the insulation member 42; and the wire 43, which leads -to the coils 44 of the electromagnet, is electrically connected to the screw 41 in any suitable manner. The return wire 45, of the coils 44, is electrically connected tothe spring 46'which is insulated from the casing by (means of an insulation member 47. Spring 46 is fixed to the armature 47 of the 'electromagnets, and the armature 47 is pivoted, an insulation bracket 48 fixed to the casing 17. Bythis means the electric current passes into the armature 47 and through contacts 49l and 50 and spring 51 to the casing 17 As is well udderstood, when the current passes into the coils of the electromagnet the armature will be drawn to the electromagnet, and the contacts -49 and 50 will be opened. The spring 46 will then -force the armature away from the electrooperation will be repeated.

In order to cause suiicientlvibration of l the casing 17 I'have provided the armature 4 7 with a weight 52. As the armature vibrates the weight is forced against the electromagnet, or against the wall of the casing, and thus causesthe entire casing, together withthe attached blade, to vibrate. An insulation member 53 prevents 'the weight from coming in contact With the casing. By this means I am able Ato obtain a vibration of the blade, parallel `withr the cutting edge thereof, without any mechanical connection between the blade and the 'mecham ismwithin the casing.r .I am thus'able to have the mechanism entirely inclosed so as .j to prevent the entrance of moisture or dirt,

and so-that the, apparatus may be cleaned at any time without danger'of injury to the delicate portions kof the mechanism.

'When it is desired to clean the'casing or remove the'guard 25 it is necessary only to sllp the casing out of the frame at either end vof the opening 12. As there is no posi# tive mechanical connection between the casmg and the' frame the casingmay be very 'easily removed orlreturned. If .it is desired to openthe casing vthe plate 54 may be removedv by rst removing screw 55.A

fixed to vsaid frame,

inclosed within said casing, ,said casing being loosely mounted in said frame whereby said casing may be vibrated relative to said frame.

4 2. Vibrating means comprising a frame, a casing loosely mounted in said frame, a

member to be vibrated rigidly mounted on said casing, an electric vibrator fixed to said casing, the armature of said vibrator being weighted, whereby saidy member is adapted to lbe vibrated relative to said frame. e

3. In a safety razor, la frame, a casing loosely mounted in said frame, a blade fixed to said casing, and a vibrator mounted in said casing and adapted 'to vibrate said blade and said frame relative to each other.

4. In a safetyrazor a frame, a guard a casing loosely mounted in said frame, a blade Xed to casing, and auvibratormounted insaid casing and adapted to, vibrate said casing and blade with reference to said frame.

5. A safety razor comprising a frame,- a guard fixed to said-frame, a casing loosely mounted 4in said frame, said guard having an elongated aperture therethrough, lugs projecting from said casing through said aperture, a blade fixed to said lugs, vibrator in said casing.

and a 6. AA safety razor comprising a frame, a

guard having an elongated aperture therethrough xed to said frame, a casing loosely mounted in said frame, a lug. projecting from said casing and passing loosely,

through said aperture, a blade having openings therethrough, said lugpassing snugly through one of said openings, a lug project- I ing` outwardly from said guard through another opening through said blade, a cap guard having a recess therein, the lug of said `guard passing into said recess, and means for holding said cap guard to said other guard.'

- 7. A'safety razor comprising a frame, a

'guard fiXed`to said frame, a casing loosely lmounted in said frame,`a blade fixed to said casing external to said guard and spaced therefrom', a second guard fixed to said other guard external to said blade and spacedVV therefrom, and a vibrator in said casing. e
